Answer:

[tex]n=3[/tex]

Step-by-step explanation:

Note that [tex]2^5*5^2=2^3*2^2*5^2=2^3*(2*5)^2=2^3*10^2[/tex].

Aha! We see a path to the solution!

We now know that our equation is actually [tex]2^3*10^2=2^{n}*10^2[/tex].

We can divide both sides by [tex]10^2[/tex] to get [tex]2^3=2^{n}[/tex].

By inspection or taking the logarithm base 2 of both sides, we see that [tex]3=n[/tex].

So, the answer is [tex]\boxed{n=3}[/tex] and we're done!

What is a word problem?

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

The population of insects is increasing by 9% each week = 0.09

At the beginning of the experiment, number of insects = 16

Number of insects increased per week

⇒ [tex]16+16(0.09)[/tex]

Let the time period be x.

Number of insects increased after 8 weeks can be found by the equation,

[tex]Future Amount = 16 (1 + 0.09)^{x}[/tex]

⇒ [tex]Future Amount = 16 (1 + 0.09)^{8}[/tex]

Hence we can conclude that the value of time period for the equation is 8.

Give a convincing argument with logical explanations that the contrapositive of a conditional is the
same as the converse of the inverse of the conditional

Answers

Answer:

see explanation. (I did this exact assignment this morning, and this is very similar to what I submitted)

Step-by-step explanation:

The contrapositive of a conditional is the same as the converse of the inverse of the conditional.

The best way to prove/support this statement is to create an example. You should start by creating a conditional; you can then form the conditional's converse, inverse, and contrapositive. Here is an example:

Conditional: If C, then D. (starting statement)

Converse: If D, then C. (conditional reversed)

Inverse: If not C, then not D. (opposite of the conditional)

Contrapositive: If not D, then not C. (reversed opposite of the conditional)

Based on the information from the example you gave, you can conclude:

The converse of the inverse: If not D, then not C. (reversed opposite of the conditional)

Because: The converse is the conditional reversed (If D, then C). The inverse of the converse, in this case, would then make it the opposite (If not D, then not C).

I have not yet received a grade on this assignment, but I know the information is correct; the amount of explanation you need to give really depends on how your teacher grades. Personally, I just submitted an example (similar to the one above) that was color-coded to help show the different parts of each statement.

The rate of change is also known as the slope or rise / run.

Slope Formula: (y2 - y1) / (x2 - x1)

First, we'll need two points that are on the line. You can choose any two points you want, as long as they are on the line.

Point 1 = (0, 1)

Point 2 = (-2, -3)

Then, we'll plug the two points into the formula and solve for the slope.

(-3 - 1) / (-2 - 0)

(-4) / (-2)

The rate of change of this line is 2.

Answer:

If its just 15 then its 1

Step-by-step explanation:

Because 15 divided by 1 is 15 which is the fraction.

Answer:

Below,...!

Step-by-step explanation:

15 is not a fraction as is you can put any number over a one and that whole number immediately becomes a fraction:

[tex]\frac{7}{1} or \frac{43}{1} or \frac{987}{1} or \frac{1}{1} or \frac{15}{1}[/tex]

Y-k = m(x-h) solve for m

Answers

Answer:

Simplifying

y + -1k = m(x + -1h)

Reorder the terms:

-1k + y = m(x + -1h)

Reorder the terms:

-1k + y = m(-1h + x)

-1k + y = (-1h * m + x * m)

-1k + y = (-1hm + mx)

Solving

-1k + y = -1hm + mx

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '-1y' to each side of the equation.

-1k + y + -1y = -1hm + mx + -1y

Combine like terms: y + -1y = 0

-1k + 0 = -1hm + mx + -1y

-1k = -1hm + mx + -1y

Divide each side by '-1'.

k = hm + -1mx + y

Simplifying

k = hm + -1mx + y

Step-by-step explanation:  Slope is the rate of change of y for each change in x.  y = 2x is a line with slope of 2.  Each time x is incremented by 1, y will increase by twice (2x) that amount.  There is no slope to a verticle line, unless you want to call it infinite.  The value of y is not defined by x.
